SMTP Relay & Email API
Two ways in. Drop our SMTP credentials into any app, or call the Email API directly. Both take minutes, both just work.
Maileroo keeps email delivery simple from the first send. Start with reliable SMTP, get 3,000 free emails per month, and use extra tools when your team needs more control. Hit the inbox every time.
SMTP2GO covers the sending basics. Maileroo gives you a simple email delivery platform with more tools built in, so your team can send, track, manage, and grow without adding extra systems.
See what happens after each send. Delivery, opens, clicks, bounces, and full logs in one dashboard, live from your first email.
Take control of your sender reputation as volume grows. Dedicated IPs are included from 250k emails a month, with no per-IP fee on top.
We generate your SPF, DKIM, and DMARC records and verify them for you. No copy-pasting from a docs page and hoping it propagated.
Invite collaborators with roles, sign in with passkeys or SAML SSO, and give every app its own scoped key. A leaked staging key can't touch production, and offboarding someone in your IdP offboards them here.
Point an MX record at us and inbound mail lands on your endpoint, parsed and ready to use. Replies, support inboxes, and anything else your product needs to read.
Ask about warmup, authentication, or a drop in placement and get an engineer who runs the platform, not a case number.
Verify your domain, swap your SMTP credentials, and you're sending. Every message tracked live, suppressions handled automatically, webhooks that retry on their own, and an engineer to ask when something looks wrong.
Maileroo is built for teams that want more than basic SMTP without paying for a heavy platform. You get a modern dashboard, real-time analytics, and per message tracking from your first send.
When an address bounces or a message needs attention, you can see it sooner and deal with it properly. Suppression handling runs on its own, and webhooks fire reliably with retries.
Start free with 3,000 emails per month. No credit card needed.
When you need help, you are not left guessing. Maileroo gives you support from people who understand email delivery and can help you get things sorted.
Our engineer-led support team is always ready to help you with any issues, ensuring your emails are delivered without a hitch.
Same support on every plan, including the free one.
Send with confidence, track every message as it moves, and tune your performance. One platform, built developer-first. And deliverability? We fine-tune it obsessively behind the scenes, so your emails land where they should.

Two ways in. Drop our SMTP credentials into any app, or call the Email API directly. Both take minutes, both just work.

Sent, delivered, opened, clicked: watch every event the moment it happens. When something breaks, the logs tell you why.

Open rates, click rates, bounces, complaints. The numbers you need to sharpen your sending, all in one dashboard.

Push bounces, opens, clicks, and deliveries straight into your application the instant they happen. Your app stays in sync without polling.

Put tracking links on your own domain. Better brand consistency, better deliverability. SSL is provisioned for you, and setup takes one click.

Retire the no-reply address. Replies land in your inbox, routed by Maileroo, so real conversations can happen.
SMTP2GO covers the sending basics with a legacy interface. Maileroo bundles sending, tracking, suppressions, webhooks, dedicated IPs, and support into one plan. Here is how they line up.
We're a small team, which means when you write in, you're talking to someone who works on the product. Startups, agencies, and growing businesses stay with Maileroo because the support is real, the pricing is honest, and the infrastructure holds up.
"I love it as an SMTP service for transactional emails. The app is fast, easy to understand and fully featured, but not overwhelming, and email delivery is super fast and reliable. Just perfect! Every time I needed to request a feature or inquire about something with the team, they responded quickly and satisfactorily, both in their Discord channel and via email."

"I have been a Maileroo customer for almost 2 years now and I am very satisfied: Sending emails is super fast and reliable. The support is great and fast (usually within 1 hour). The interface is functional yet easy to use. You pay much less at Maileroo than at other providers without compromising on quality. In short, a great company to work with as an agency!"

"Using Maileroo for half a year now. Api and its documentation is simple, straightforward and just works. What truly makes the difference is the fast, personal support. Support is always quick to respond and to find a solution. Requests or suggestions are taken seriously and often translated into practical improvements. That level of personal involvement and service is rare and makes Maileroo a solution I can confidently recommend. Experience with mailgun, mailjet, sendgrid, resend and Maileroo takes the cake."
